We reserved too late to get a pair of seats together, so we had the "singles" on opposite sides of the aisle.
We did *not* find it at all convenient to talk, and it was almost impossible even to signal to get the other person's attention. That was okay, given we really wanted to rest. But there are other flights where we do want to sit together, and this seating would not have been at all good for that.

I should add that we were surprised and pleased with the comfort of the seats, and with the service.
